FIELD OF THE INVENTION

The invention relates to personal care compositions comprising carboxylated starch ester polyglucose polymers. More specifically, the invention relates to hair fixative compositions comprising carboxylated starch ester polyglucose polymers that are soluble in alcohol based solvent systems.

BACKGROUND OF THE INVENTION

Polymers used in personal care applications, such as hair styling and hair fixing, have conventionally been made using synthetic materials. In order for the polymers to be suitable in such personal care applications, they must be soluble in alcohol based systems, and in the case of aerosol based hair sprays, they must also be compatible with the propellant. Conventional synthetic polymers are generally inexpensive and provide acceptable performance; however, because they are not made from renewable resources, they are not sustainable. In addition, replicating the cost and performance of synthetic polymers is not easy.

Accordingly, there is a need for personal care polymers made from renewable sources that provide equal to or better performance at comparable costs than their synthetic alternatives and that are soluble in alcohol based systems, such as ethanol based systems and optionally, that are compatible with propellants, such as dimethyl ether.

SUMMARY OF THE INVENTION

In an aspect, the present invention relates to a hair fixative composition comprising at least one carboxylated starch ester based polyglucose polymer; an alcohol based solvent system; and a cosmetically acceptable additive. The polyglucose polymer is obtained by reacting at least one starch ester with an anhydride, such as a cyclic anhydride or an acylic anhydride or mixtures thereof, and the polyglucose polymer is soluble in the alcohol based solvent system. The starch ester may be obtained by reacting starch with at least one acyclic anhydride, at least one cyclic anhydride or mixtures thereof.

In another aspect, the present invention relates to a method of preparing a hair fixative composition comprising reacting at least one starch ester with an anhydride, such as a cyclic anhydride or an acylic anhydride or mixtures thereof, to form a starch ester based polyglucose polymer. In a further step, the method comprises dissolving or suspending the starch ester based polyglucose polymer in the alcohol based solvent system. The starch ester may be obtained by reacting starch with at least one acyclic anhydride, at least one cyclic anhydride or mixtures thereof.

In yet another aspect, the present invention relates to the use of the carboxylated starch ester based polyglucose polymer as defined herein as a hair fixative polymer in a hair fixative composition, as well as a method of styling hair, comprising applying the carboxylated starch ester based polyglucose polymer as defined herein to hair.

General Synthesis Method for Polyglucose Polymers

Starch Acetate (or Propionate) Succinate Octenyl Succinate Polymers

A reaction vessel equipped with an agitator and condenser kept under nitrogen atmosphere and immersed in an oil bath for heating was charged with specified amount of (see Table 2) starch, acetic acid, sodium acetate (or sodium hydroxide) and acetic anhydride (or propionic anhydride). The amount of acetic (or propionic) anhydride was adjusted to take care of the moisture level generally present in the starch. The mixture was heated to 125-130° C. under stirring until the reaction showed completion as monitored by IR for the disappearance of the anhydride peak. Once all the acetic (or propionic) anhydride was reacted, the reaction mixture was cooled to about 100-110° C., OSA was added and the stirring continued at 110-115° C. until the reaction showed completion as monitored by IR for the disappearance of the anhydride peak due to OSA. Succinic anhydride was then added to the reaction mixture and the stirring was continued at 110-115° C. until all the succinic anhydride reacted as monitored by IR. The reaction mixture was then cooled to 70° C. and then poured to a vigorously stirred water (about 5 times the weight of the reaction mixture) at ambient temperature. After stirring for 30 min., the solid separated was filtered, washed with water until all the residual acetic acid was washed off and dried in oven at 45° C. overnight to give solid product.

Several other starch acetate (or propionate) succinate octenyl succinate using different starch source were prepared using essentially the same procedure mentioned above but using different quantities of raw-materials as detailed in Table 2 (Examples 1-13 and 16-26)

Starch Acetate Octenyl Succinate Phthalate Polymers

These were made using essentially the same procedure as described above, except that after all the acetic anhydride was reacted, specified amount of phthalic anhydride was added followed by OSA after 2 hours of addition of phthalic anhydride. Details of the raw-materials to make these products are detailed in Table 2, Examples 14, 15 and 27.

A. Subjective Test Procedures

Subjective evaluations as provided in the Examples comparing AMPHOMER® polymer, each using 3.5 wt % of the polymers using 80 wt % VOC ethanol-water and 40 wt % DME or as otherwise identified using statistical design method at 95% confidence level were conducted. The results of the Subjective Evaluations conducted are reported in the Tables that follow as indicated.

The following procedures were used to conduct the evaluations of the subjective performance of the polyglucose polymers of the present invention.

Gloss:

Gently handle the swatches so as not to break the films. Visually inspect the swatches to determine which has more shine/gloss.

Stiffness:

Gently handle swatches and feel for differences in stiffness. Using two fingers, hold the middle of the swatch in a horizontal position—does one bend more than the other? Choose the one that is more rigid.

Spring:

While holding the swatch in one hand, gently pull on an edge with the other hand three times only. Look for spring back, and bounce. The more elastic the better the Spring.

Webbing:

While holding the swatch in both hands, gently pull outward on the edges approx. 4″. (Do this three times only to avoid damage to the bonds. If the bonds are destroyed then the dry combing may appear to be easier to comb). The more net like the better the Webbing.
Dry Comb:
Comb through each swatch (5) times and evaluate ease of combing. Choose the one that combs more easily.
Flake:
Visually inspect both swatches after combing. Check the teeth of the comb for flake accumulation. Holding the swatch at the bound end run your fingernail down the length of the tress then inspect. Choose the one with more flakes.
Anti-Stat:
Holding swatch at bound end comb through vigorously 10 times then evaluate for extent of fly aways generated. Choose the one with more fly aways.
Feel:
Handle swatches and determine preference. Choose the one that feels more silky/cleaner.

C. Procedure for Determining High Humidity Curl Retention (HHCR)

The following procedures were used to conduct the evaluations of the objective performance of the polyglucose polymers of the present invention as determined by high humidity curl retention. The high humidity curl retention properties of hair styling compositions including polyglucose polymers of the present invention were measured. The tests were each conducted at 72° F. (22° C.) and 90% Relative Humidity over a period of 24 hours. The tests were performed on 10″ long×2-gram swatches of European virgin brown hair (9 replicate swatches per sample). Curl retention testing is run in a humidity chamber set at 70° F./90% Relative Humidity for a total of 24 hours. Readings for % Curl Retention are read and recorded at time intervals of 15, 30, 60, 90 min, 2, 3, 4, 5, and 24 hrs. The hair styling compositions were tested according to the following procedures:

• • 1. Wet hair swatch, comb through to remove tangles and squeeze out excess water (run swatch between thumb and index finger).
  • 2. Apply sample to swatch, gently “work into” swatch and comb through.
  • 3. Roll swatch on ½″ diameter Teflon mandrel. Carefully remove rolled swatch from mandrel and secure with two hair clips.
  • 4. Place curls on tray and dry in oven overnight.
  • 5. Remove dried curls from oven and let cool to room temperature.
  • 6. Suspend curls, from bound end of swatch, on graduated clear, transparent curl retention boards.
  • 7. Remove clips from curls and gently unwind with glass rod making sure to “break” the curl.
  • 8. Take initial curl length readings before placing boards and curls into environmental chamber (70° F., 90% relative humidity).
  • 9. Record curl lengths at the 15, 30, 60, 90, 2, 3, 4, 5, and hour time intervals.
  • 10. At conclusion of test, remove boards and curls from chamber.
  • 11. Clean used hair swatches.
  • 12. Calculate % Curl Retention and comparison of samples.
    The Samples were prepared as follows:

HHCR was run in a constant temperature and humidity chamber. Curls were rolled on a mandrel and allowed to dry overnight. The curls were then sprayed with the polymer solutions (3.5 wt % polymer using 80% VOC ethanol-water and 40% DME) and allowed to dry. Then the curls were hung on a board placed in the oven and the percent of curl loss was tracked over 24 hrs.

The high humidity curl retention properties of hair styling compositions including polyglucose polymers of the present invention according to the Examples as shown in the following Tables as indicated were measured and compared to the use of AMPHOMER® polymer in the same hair styling composition.
